LAWRENCE V7'. L'UFF, OF SHAKER. HEIGHTS, OHIO, ASSIGNOR TO THECONSOLIDATED IRON-STEEL MANUFACTURING COMPANY, OF CLEVELAND, OHIO, ACORPORATION OF OHIO BOILER STAND Application filed November 23, 1929.Serial No. 409,305.

This invention relates to boiler stands of the type employed forsupporting a domestic hot water boiler.

The objects of the present invention are to provide a novel form of suchstand which shall be of extreme simplicityV and of economic manufacture,and more particularly to provide such a stand of a minimum number ofprincipal parts.

Another object of the invention is to provide such a form of said partsthat a large number of the same may be conveniently cast in closelyspaced relation in a single mold. And still another object of theinvention is to provide by an arrangement of extreme simplicity, meansfor adjusting the stand to accommodate various boiler sizes.

The exact nature of my invention together with further objects andadvantages thereof will be apparent from the following description takenin connection with the accompanying drawings in which Fig. l shows inelevation, arranged in corresponding relation7 the three principal partsfrom which my stand is assembled; Figs. 2 and 3 are plan and elevationviews respectively of the stand assembled to accommodate one of thepossible sizes of boiler; Fig. 4 is a section as in the plane of line 44, Fig. 2; Figs. 5 and 6 correspond generally with Figs. l and 2 showinghowever a modification of my invention; Fig. 7 is a detail showing theparts appearing in Fig. 6 adjusted to an optional relation; and Fig. 8is a plan view of the part E appearing in FVith reference now to thedrawings and particularly now to Figs. 1-4 thereof, my boiler stand isassembled from three principal parts A, B, and C. These parts are so aswill appear. Each part however comprises a leg member l and a straightintegral arm member 2 extending perpendicularlytherefrom.

Oneend of each leg member 1 is notched generally similar although notidenticallyv Fig. l. f Thus the arm member 2a is arranged in the planeintermediate those of the arml members 2b and 2c. j n n Each of the armmembers has in its end portion a plurality of openings, 4, 5 and 6, :55three being shown, spaced therealong. The series of openings of each armcorresponds with those of the other arms, that is, the openings 4 of thearms are all equidistant from their respective leg members l, andlikewise the openings 5 and in each of the arms i correspond in distancefrom their respective leg members. Thus each arm-2 has one of a set ofopenings 4, one of av set of; openings 5, and one of a` set of openings6. g5

From what has thus far been described it ...will be apparent that .thevparts A, B and C may be assembled as indicated Figs. 2 and 3 by asecuring Vmember D, indicated as a bolt, extending through the severallopenings of y'zo any of the described sets thereof. It will also beapparent that with the arms 2 of the parts spaced at yas indicated Fig.2, the legs 1 will be equally spaced to define a cylinder of which thesecuring member D is central, $5 so that the notches 3 of the legs willlie equally i spaced in the corres onding circle to receive theedgeflange of a oiler to be supported.`

As indicated Fig. 2 the set of openings numbered 6 is employed byaligning the same eo to receive the member D. The central setof openingsnumbered 5 might be similarly employed to reduce the size of the circledefined by the notches 3, to accommodate a boiler of smaller diameter;andthe third setof open- 35 ings 4 mightbe similarly employed to reducelthe size of thelcircle denedbythe notches 3,

to accommodate a boiler ofstillsmaller diameter. l' r j In order tomaintain .the angularity of thee@ arms 2 as indicated in Fig. 2, whenthe parts i are assembled, I provide interlocking means upon thecontacting faces of the arms. The interlock 'comprises acorrugation-like face formation 7 on the end portion of each arm 2, M95in which the openings 4, and 6 arelocated. 4 As indicated particularlyin Figs. 2 and 4 these corrugationformations arearranged on the lowerface of the arm 2b, bothfaces-of the arm 2a, andthe upper face only ofthe 'arm 2c.. 1f.se

is adjusted.

With reference now to Figs. 5-7 inclusive of the drawings whereinsimilar or corresponding parts are designated by similar orcorresponding reference characters to those appearing in Figs. 1-4, itwill be observed that the parts E, F and and their general assembledarrangement aresubstantially similar to what has been disclosed withreference to parts'A, B and C. The principal exception is that here theleg 2g Vof one of the three principal parts is longer, whereas the legs2e and 2f of the other'two principal parts are shorter, than before.Also the interlocking deformations 7 run transversely of the arms 2e and2f for interengagement therebetween, and run lengthwise of the arm 2eand transversely of the arm 2g for interengagement therebetween asindicated. Thus the parts are assembled here with their arms incruciform arrangement and rectangular ,relation as indicated Fig. 6, tolocate the notches 3 of their legs l in the circumference of a circle asindicated in dot-dash lines at 9. In Fig. 6' the securing member D isarranged in` the set of openings 4,' whereby the standV is adjusted toaccommodate the smallest size of boiler, As shown in Fig. 7 the member Dmay instead be secured in the set of openings 6 of the arms 2, obviouslyproviding an adjustment to accommodate the largest size of boiler.Likewise were the openings 5 aligned and the member D securedtherethrough, the adjustment to an intermediate size would bek had.

l. An adjustable boiler stand comprising,

in boiler-supportingk position, a plurality of circumferentially spacedvertical leg members and a corresponding plurality of-arm members eachextending radially inwards from its leg member, the' adjacent ends ofsaid arm members being arranged in parallel stacked relation, each armmember having a plurality of through openings spaced therealong, and acentral securing member extendy,

ing Vthrough a corresponding opening of each arm member to maintain theparts in A the described relation, said securing member being adaptedtoextend through any corre-v signature.

ietsjes" radial relation one arm having corrugations on a lower portionthereof, another arm having corrugations on an upper portion thereof anda third arm having corrugations on both upper and lower portionsthereof, the corrugations of one arm meshed with those of another tomaintain said arms in predetermined angular relation against rotation ineither direction at all radial adjustments.

2. An adjustable boiler stand comprising, in boiler-supporting position,a plurality of circumferentially spaced vertical leg members andacorresponding plurality of arm members each .extending radially inwardlyfrom its leg member, the adjacent ends of said arm members beingarranged in vparallel stacked relation, each arm member having anvopening therethrough, and a securing member extending through all ofthe o en.

ings to maintain the parts in the described relation and to maintain thearms against relative movement radially, one armvhaving corrugations ona lower portion thereof, another arm having corrugations on an upperportion'thereof and a third arm having corrugations on both upper andlower portions thereof, the corrugations of one arm meshing with thoseof another to maintain said arms in predetermined angular relationagainst rotation in either direction.

In testimony whereof I hereby affix my LAWRENCE w. Lern.
